[Elecraft] Need Help

Hi, Lou,

My advice is to check out EVERYTHING there is to check about T5.  Is it
wound correctly.  Does the green start winding coincide with the red start
winding?  This is a biggie!.  If you aren't careful about winding
transformers, start windings can become backwards very easily.  Did you
strip enough insulation so that the windings are making contact?  Look for
shorts, cold solder joints, mis-installed Q18.  This VCO really does work,
and it depends a lot on doing T5 correctly in all aspects.

Good luck,

Bill Spaulding
